Drag & Drop n' Swipe Recyclerview

Drag & Drop n' Swipe Recyclerview

Highly customizable Android library written in Kotlin that uses AndroidX and extends RecyclerView to include extra features, such as support for drag & drop and swipe gestures, among others. It works with vertical, horizontal and grid lists.


Support this library

The creation (and maintenance) of this library requires time and effort. If you find it useful and want to support it, please use the link below:

How to use it

1. Reference the library

Add the library to your project via Gradle:

dependencies {
    implementation 'com.ernestoyaquello.dragdropswiperecyclerview:drag-drop-swipe-recyclerview:0.5.1'

NOTE: Make sure you are using AndroidX instead of the old support libraries; otherwise this library might not work.

2. Add the list to your layout

Place the DragDropSwipeRecyclerview inside your layout using XML:

<!-- layout/view_layout.xml -->
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"



As you can see in the code above, we specify the list item layout through the attribute item_layout. This way, the library will take care of inflating the item layout automatically, so you won't have to do it manually in the adapter.

In addition, in this example you can also see that the optional attribute divider is being used to specify the drawable that will be displayed between list items (for more information about available attributes, see Customization).

Referenced resource files

Just in case they are of any help, these are the example resource files referenced in the code above:

<!-- layout/list_item_layout.xml -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
<!-- drawable/list_divider.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    <size android:height="1dp" />
    <solid android:color="#e1e1e1" />
<!-- drawable/ic_drag.xml -->
<vector xmlns:android="http://schemas.android.com/apk/res/android"
        android:pathData="M7,19V17H9V19H7M11,19V17H13V19H11M15,19V17H17V19H15M7,15V13H9V15H7M11,15V13H13V15H11M15,15V13H17V15H15M7,11V9H> 9V11H7M11,11V9H13V11H11M15,11V9H17V11H15M7,7V5H9V7H7M11,7V5H13V7H11M15,7V5H17V7H15Z" />

3. Create the adapter

The next step is to implement your adapter (and viewholder) by extending the class DragDropSwipeAdapter<T, U>, where T will be your item type and U will be your viewholder type:

class MyAdapter(dataSet: List<String> = emptyList())
    : DragDropSwipeAdapter<String, MyAdapter.ViewHolder>(dataSet) {
    class ViewHolder(itemView: View) : DragDropSwipeAdapter.ViewHolder(itemView) {
        val itemText: TextView = itemView.findViewById(R.id.item_text)
        val dragIcon: ImageView = itemView.findViewById(R.id.drag_icon)

    override fun getViewHolder(itemLayout: View) = MyAdapter.ViewHolder(itemLayout)

    override fun onBindViewHolder(item: String, viewHolder: MyAdapter.ViewHolder, position: Int) {
        // Here we update the contents of the view holder's views to reflect the item's data
        viewHolder.itemText.text = item

    override fun getViewToTouchToStartDraggingItem(item: String, viewHolder: MyAdapter.ViewHolder, position: Int): View? {
        // We return the view holder's view on which the user has to touch to drag the item
        return viewHolder.dragIcon 

This is just a basic implementation, but there are more methods in the adapter that you can override to customize the list and its behaviour (see Customization).

4. Setup the list

Finally, you should setup the list to make it work and take advantage of its features.

Set up the adapter

Inside onCreate or onCreateView, find the list and set it with a layout manager and your adapter:

val dataSet = listOf("Item 1", "Item 2", "Item 3")
mAdapter = MyAdapter(dataSet)
mList = findViewById(R.id.list)
mList.layoutManager = LinearLayoutManager(this)
mList.adapter = mAdapter

Set up the orientation

Then, specify the list orientation. For example:

mList.orientation = DragDropSwipeRecyclerView.ListOrientation.VERTICAL_LIST_WITH_VERTICAL_DRAGGING
Using grid orientation with dividers

Take into account that if and only if you want to show dividers in a list with a grid orientation, you also need to set one of these two properties:

// Set this property if your grid can be scrolled vertically
mList.numOfColumnsPerRowInGridList = <numberOfColumns>


// Set this property if your grid can be scrolled horizontally
mList.numOfRowsPerColumnInGridList = <numberOfRows>
Restricting swiping and dragging directions

In case you want to disallow dragging or swiping actions in certain directions, you can do the following:

// This disallows swiping items to the right


// This disallows dragging items up

Set event listeners

Finally, create event listeners for the events you want to handle. For example, these are the listeners for actions of swiping, dragging & dropping and scrolling:

private val onItemSwipeListener = object : OnItemSwipeListener<String> {
    override fun onItemSwiped(position: Int, direction: OnItemSwipeListener.SwipeDirection, item: String): Boolean {
        // Handle action of item swiped
        // Return false to indicate that the swiped item should be removed from the adapter's data set (default behaviour)
        // Return true to stop the swiped item from being automatically removed from the adapter's data set (in this case, it will be your responsibility to manually update the data set as necessary)
        return false

private val onItemDragListener = object : OnItemDragListener<String> {
    override fun onItemDragged(previousPosition: Int, newPosition: Int, item: String) {
        // Handle action of item being dragged from one position to another

    override fun onItemDropped(initialPosition: Int, finalPosition: Int, item: String) {
        // Handle action of item dropped

private val onListScrollListener = object : OnListScrollListener {
    override fun onListScrollStateChanged(scrollState: OnListScrollListener.ScrollState) {
        // Handle change on list scroll state

    override fun onListScrolled(scrollDirection: OnListScrollListener.ScrollDirection, distance: Int) {
        // Handle scrolling

Then, set the listeners...

mList.swipeListener = onItemSwipeListener
mList.dragListener = onItemDragListener
mList.scrollListener = onListScrollListener

And that's it! Your list with support for swipe and drag & drop should be fully working now.


DragDropSwipeRecyclerView customization

There are several XML attributes that you can set in the DragDropSwipeRecyclerView in order to customize the style of the list and its items:
